    摘要： A pharynx protector may include a proximal end and a distal end, the distal end being adapted to be inserted into an oesophagus of a patient. The protector may include an elongated tubular part and a distally located receiving portion for receiving a puncture needle during a laryngectomy, wherein the tubular part is substantially flexible. The receiving portion may include a first opening, communicating with a lumen of the tubular part, such that a guide wire may be inserted through the first opening and further passed proximally out of the pharynx protector. A surface of an inner wall may be of a rigid material.

    摘要： The apparatus and method invented are operating upon a digital image signal obtained from an image sensor. The sensor is covered with different colored filters and is only able to record the color transmitted through each specific filter into the photosite or pixel. This type of sensor is known as a color filter array or CFA sensor. The different colored filters are arranged in a predefined pattern across the sensor. To obtain a full color image the missing color information is estimated by a set of weighed values obtained by an inverted gradient function. The set of weighted values is found from the neighboring pixels in the four compass directions, north, east, west and south or is found horizontally and vertically. The surrounding pixels are corrected by the chrominance channel to better fit the center pixel in the luminance channel, prior to using the gradient functions. The chrominance channel is interpolated in a similar manner and is also corrected to better fit the center pixel before the inverted gradient functions are applied.
